Method for allocating frequency channels to a plurality of neighboring access points

A device for allocating frequency channels, the device comprising a processor and a receiver configured to carry out computer program instructions stored in memory, the computer program instructions comprising:

• receiving wireless medium usage information from a plurality access points (APs), wherein the wireless medium information includes usage of the wireless medium over multiple periods of time for each AP of the plurality of APs;
• computing an activity-based parameter between each AP of the plurality of APs based on the wireless medium usage information, wherein the activity based-parameter is indicative of a similarity between a plurality of use patterns of the wireless medium over multiple periods of time, and wherein each use pattern of the wireless medium is determined for one period of time of the multiple periods of time, wherein each use pattern is weighted according to how recent the wireless medium usage information is for a given period of time, wherein the similarity between the plurality of use patterns is calculated using a dynamic time warping algorithm;
• and
• minimizing time overlap of the usage of the wireless medium by the plurality of APs by allocating a frequency channel to each AP of the plurality of APs based on the computed activity-based parameter.
